Abstract

Modern personal computer memory includes several microchips placed on the one circuit board (module). There is Read Only Memory (ROM) always presented in every module. ROM is needed for storing data that has to be stored and used without any changes.

Memory cards for laptop

As a rule, the ROM module contains computer software responsible for loading the operating system while the PC is switching on.

The main ROM microchip containing the main BIOS code, places on the motherboard. BIOS subprograms and drivers, required to activate and start all the system components, are located on the adapter card.

It goes without saying that chips ROM placed in the Random Access Memory (RAM) module, have to be fully compatible with the motherboard of Brand Name class devices. Being used mostly in brand computers, Kingston and Transcend memory cards for laptop and PC fully meet the requirements listed above.

Today the most common RAM in laptops and stationary PC is Dynamic Random Access Memory (DRAM). DRAM chip divides in a DDR, DDR2 and DDR3 type. Rarely EDO and FPM memory is used in Brand Name devices.

RAM cars for laptopHigh-speed performance of the laptop, wide range of features for users, power-consuming games - everything directly depends on the built-in Random Access Memory (RAM).

It's recommended to use 4 Gb or more for comfort operating with OS Windows 7 if you work in particular applications.

Almost all modern laptop models allow to widen memory by means of using additional slots. Some models also provide up to 16Gb of RAM.

Take care of your Laptop to get maximum service from it

Laptops motherboards

Laptop motherboards get more exposure to damage compared to the desktop motherboards. Despite the fact that they stay cleaner, the likelihood of being exposed to heat to heat is higher. They also get more exposure to impact because the computer is regularly carried around.

Laptops motherboards

During laptop transportation, it is important to ensure that you use a case specifically designed to be used for carrying a laptop so that you prevent the impact forces from hitting your laptop. Additionally, many laptops come with vents on back part and bottom. It is difficult to cool the inside of your laptop because of the confined space so it is important that you ensure that the vents remain unblocked as you work on your laptop.

You should learn where the vents are on your laptop to ensure that you do not block them while working. This helps ensure that laptop motherboards cool effectively.

Upgrading a Macbook Pro

Tuesday 08 January 2013 at 11:26 pm

If you're of the mindset that a Macbook Pro can't have its hardware upgraded, you're in for a surprise - for a surprisingly reasonable sum, you can double your hard-drive space and your RAM, giving you a space and performance boost that you're probably going to enjoy, somewhat! So, why should you consider upgrading, and what should you look for?

RAM for Mac mini

Tuesday 08 January 2013 at 11:20 pm

The Other World Computing company started selling the RAM modules for Mac mini models released five months ago. Previously there was written in the official specifications of Apple that new Mac mini models were to operate with memory modules of the overall maximum volume of 8 Gb.
However, already today you may buy modules of 16 Gb from Other World Computing, herewith, the company guarantees their normal performance.
Other World Computing offers four RAM modules sets as following:
Two 1333 MHz DDR3 modules of 2 Gb at the price of 38$;
Two 1333 MHz DDR3 modules of 4 Gb at 80$;
One 1333 MHz DDR3 module of 4 Gb + one 1333 MHz DDR3 module of 8 Gb at 750$;
Two 1333 MHz DDR3 modules of 8 Gb at 1400$.

Hybrid Memory Cube

Tuesday 08 January 2013 at 11:16 pm

Hybrid Memory Cube
Two giants of the memory manufacture - IBM and Micron Technology - are going to launch series production of the principally new memory. The CMOS interlayer connection technology - through-silicon via, TSV – is to be applied in the memory for the first time.

The name of the memory is HMC (Hybrid Memory Cube).

These RAM chips are to be released at the conference of Intel designers in September, 2012.

It is joint working of Intel and Micron, IBM worked on the TSV technology. All the details and nuances about this work IBM is going to tell at the IEEE International Electron Devices Meeting conference on December, 5.

Components of HMC are to be manufactured at the IBM progressive division located in New York. During producing, there is used the 32 nanometers HKMG technology.

What laptop memory do i need?

Tuesday 08 January 2013 at 11:10 pm

What laptop memory do i needThose users of laptops who decided to add memory modules by themselves should know, that it’s not enough to say in the shop “give me memory for my laptop” and then having returned home, to pull the lid away and install the memory into any slot of the same size. Do not torture yourself with questions like "what laptop memory do I need".

In up-to-date laptops there is used DDR SDRAM (Double Data Rate SDRAM). It supports transmission of not one data bursts, but two per one clock cycle in order to increase bandwidth of memory. To promote this type of memory, manufacturers started specifying memory speed as frequency of transmitting one data burst (i.e the effective one), not as real frequency.

Types of laptop memory

Monday 19 December 2011 at 1:54 pm

Types of RAMToday there are 4 types of laptop memory, such as: SO DIMM DDR, SO DIMM DDR2, SO DIMM DDR3 and Micro DIMM.

Types listed above don’t include RAM for desktops (personal computers) that some sellers successfully sell as if it’s for laptops and some users successfully buy it. Moreover, some models of notebooks are equipped with additional memory slots that are located under a keyboard, not under a lid that is easy to open.

So that, upgrading process is getting more difficult, in addition, you may break something essential. Your notebook will not start to run with the module that is fixed askew, as well with modules that are working at high frequency of bus or that have memory more than acceptable.
